Kintz Plastics works with a wide range of thermoplastics. The optimal material for a part is based on cost, performance and appearance.
Kintz Plastics keeps current on developments of new materials for thermoforming to insure that our customers get the very latest technology to suit their needs.

Selecting a Material

There are many factors that go into the selection of the best Material for your application. The Kintz Plastics' design and engineering team can recommend a material based on these factors:

Rigid or flexible - Does the part need to be stiff and rigid or have some flexibility?
• Appearance - How important is appearance compared to strength, weight, durability and use?
Cost - Do you need the least expensive part or are other factors important?
• Finish Options - Will the part be painted or can a material be used that has the desired color and surface so no painting is required? Also will text or graphics be printed on the part?
• Conductivity - Should the part be non-conductive, as most materials are, or should a conductive coating be used?
• Compatibility - What other material does the part come in contact?
• Weight - Different Materials have different densities. Is weight a factor over strength or appearance?

Types of Material:

HIPS (High-Impact Polystyrene)

High Impact Polystyrene (HIPS) contains 5 to 10% rubber (Butadiene) contents and is particularly useful in the manufacturing of parts which require a high degree of impact resistance.

ASA (Acrylic Styrene Acrylonitrile)

Acrylonitrile Styrene Acrylate (ASA) - ASA is produced by introducing a grafted acrylic ester elastomer during the copolymerization reaction between styrene and acrylonitrile. Acrylonitrile styrene acrylate material has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing, and high gloss. Acrylonitrile styrene acrylate (ASA) was first introduced by BASF in about 1970 as Luran S. The intent was to create a material similar to ABS but with better weather resistance. Because of this attribute acrylonitrile styrene acrylate has been used heavily in the automotive industry, as well as several other outdoor applications.

ABS (Acrylonitrile-Butadiene-Styrene) and ABS blends

ABS is manufactured by combining three different compounds: acrylonitrile, butadiene, and styrene. This blend of compounds results in ABS having the qualities of each material to different degrees. ABS is one of the most versatile plastics available and is a very cost effective material for many applications.


Commonly known as Plexiglass. Acrylic is an excellent material for a wide variety of applications. Acrylic sheets are about half the weight of glass, however many times stronger. Acrylic is resistant to moisture and many chemicals. Acrylic can be easily cut, drilled, cnc machined, fabricated and screen printed.

PC (Polycarbonate)

Polycarbonate (PC) is a linear polycarbonic acid ester prepared from a dihydric phenol. Polycarbonate possesses extraordinarily good dimensional stability with a high impact strength which is maintained over a wide temperature range. This makes PC ideal for the manufacture of laboratory safety shields, vacuum desiccators and centrifuge tubes.

HDPE (High-Density Polyethylene)

These sheets can be heat formed, shaped and welded to fabricate ducts, hoods, and much more. They have excellent corrosion resistance to a wide range of items. Cannot be cemented but are easily welded with plastic welder. Can be cut with a carbide tipped blade and drilled with regular metal bits. Not UV stabilized but meets FDA standards. The High Density Polyethylene has a density .Density 0.95. Rigid, good impact resistance and abrasion resistance. Color white; translucent. Working temp. -60° to 180° F. Forming temp. is 295°F. Meets FDA standards. The 3/8" and 1/2" of the 48" x 96" sheet are stress relieved.

FIMWPE (High Molecular Weight Polyethylene)

TPO (Thermoplastic Poly-Olefin)

A trade name that refers to polymer/filler blends usually consisting of some fraction of PP (polypropylene), PE (polyethylene), BCPP (block copolymer polypropylene), rubber, and a reinforcing filler. Common fillers include, though are not restricted to talc, fiberglass, carbon fiber, wollastonite, and MOS (Metal Oxy Sulfate). Common rubbers include EPR (ethylene propylene rubber), EPDM (EP-diene rubber), EO (ethylene-octene), EB (ethylbenzene), SEBS (styrene-ethylene-butadiene-styrene).

PVC Alloys (Flame Rated Polyvinyl Chloride)

PVC sheets are produced by calendaring, spread coating or extruding, and typically are reinforced with polyester or glass-fiber mats or scrim. PVC sheets contain plasticizers and stabilizers, as well as other additives to impart flexibility and achieve other desired physical properties.

Conductive Plastics

      PETG (Polyester Terephthalate Glycol)

PETG has many of the advantages of polycarbonate and is more cost effective. Its impact strength is superior to acrylic, however, it scratches easier. PETG is offered in general purpose grades as well as UV resistant grades that are recommended for weather resistance.

Mixing Resins: The same resin does not have to be used for both sides of the part. Compatible resins can be used if different characteristics are needed on each half of the twin-sheet part.

     ABS and PETG

ABS stands for Acrylonitrile Butadiene Styrene. It basically a form of Styrene plastic with an added elastisomer. ... PETG is a nice vacuumformable clear plastic. Affordable too. It has some of the same problems with overheating and boiling that ABS has.

Acrylic and PETG

PETG is polyethylene terephthalate glycol. PETG is a copolyester with high clarity. PETG sheets are very durable, dimensionally stabile and have a high impact resistance. PETG sheets are stronger than acrylic and less expensive than polycarbonate. PETG is commonly used for vacuum forming, signs and pop displays.

 There are many types of plastics that can be thermoformed and we have worked with a large variety over the years. The two most common are ABS and PVC.
